What significant change occurred to Delta Kappa Epsilon during the Civil War?

During the Civil War, Delta Kappa Epsilon faced substantial challenges that impacted its operations and membership. The correct response highlights that five chapters closed permanently during this tumultuous period. This was primarily due to the war causing a decline in active members, as many students left their studies and universities to enlist in the military. The closure of chapters was a direct consequence of this loss of membership and the overall disruption the war brought to college life.

In contrast, the other options do not accurately reflect the historical context of DKE during the Civil War. The war stunted growth rather than accelerated it, making expansion unlikely during this period. There was no evidence suggesting that DKE gained numerous national chapters during the Civil War; instead, the organization faced more closures than additions. Additionally, becoming the largest fraternity in the U.S. did not occur during this era—DKE's growth and prominence developed more significantly in later years, especially after the war ended. These factors collectively confirm why the closing of five chapters is a significant aspect of DKE's history during the Civil War.
